  • The Bread Baking Bandit Yeast rises because it is living in a single-celled organism. When yeast is added to flour and water, the yeast ferments to form alcohol and carbon dioxide. Fermentation includes both glycolysis and several reactions that regenerate pyruvate. Glycolysis is the breaking down of starch and sugar monomers. As the yeast feeds on the sugar monomers, it releases carbon dioxide in the process. CO2 and alcohol fill the air bubbles in the bread. The gluten traps the CO2 and the bubbles expand - causing the bread to rise.

  • Mechanism of Anthrax Toxins.flv Anthrax is an acute infectious disease caused by the spore-forming gram positive, aerobic bacterium Bacillus anthracis, whose pathogenesis is primarily the result of a tripartite toxin. This toxin is composed of three proteins: the Protective Antigen (PA), the Edema Factor (EF) and the Lethal Factor (LF). These proteins work together to enter a cell and disrupt the signaling pathways. Secreted from the bacteria as nontoxic monomers, these proteins assemble on the surface of Anthrax Toxin Receptor (ATR)-bearing eukaryotic cells to form toxic noncovalent complexes. The process starts when the 83 kDa PA (PA83) monomers bind to the ATR Receptor. Once bound, a 20 kDa N-terminal fragment (PA20) is cleaved off of PA83,leaving behind the remaining 63 kDa portion (PA63). PA63 rapidly oligomerizes to form a heptamer pre-pore,which then associates with up to three molecules of EF and/or LF. The cell then endocytoses the complex and carries it to an acidic compartment, where the low pH causes a conformational change in the PA63 pre-pore that forms a cation-specific channel and allows the EF and LF to enter into the cytosol. Once in the cytosol, the EF and LF then carry out their respective damage-inducing processes, ultimately causing Apoptosis. Anthrax is a disease that has plagued man and his livestock for centuries, causing it to be one of the most well-studied and understood diseases. This animation provides an overview of the mechanism of Anthrax toxin in case of pulmonary ...

  • IgG Structure As seen in the movie, although the entire antibody is composed of individual monomeric units (primary structure), the monomers align themselves in a way that is most favorable (when speaking of interactions: Van der Waals, Hydrogen bonding, etc.) This is called its tertiary structure. The tertiary structure of a protein, in this case an antibody IgG, allows it to bind to only specific molecules, its respective antigen. The antigen binding site is shown, where the light and heavy chains meet (toward the end of the "arms"). These principles lead to the proof of concept that function follows form. Depending on the specific physical conformation of a molecule (in this case the IgG), the function is then assigned. The specific amino acid sequence allows the antibody to conform into a preferred tertiary structure , which will only bind specific antigens that fit precisely.

  • The Secrets of Burning Fat - A Protein Rich Diet For the full info visit - Download the iPhone App - bit.ly Download the iPhone App - bit.ly The Top Muscle Building Protein Sources Protein is the most important nutrient for muscle growth, and this any seasoned bodybuilder can tell you. Novices take heed: If you aren't going to provide your body with the necessary amount of muscle building protein that it needs to sustain muscle growth, you will not see any significant gains, no matter how much effort you put into your workouts. So, why is protein so important, and what are the best muscle building protein sources? Let's figure it out. Protein comprises a chain of smaller monomers called amino acids, and it is a macromolecule. Protein, once it is consumed and digested, is broken down into individual amino acids, and these are used for thousands of bodily functions. Getting the ideal muscle building protein is very important for people who are looking to build their muscle size and strength. Protein is not only important for optimizing the muscle building process but also crucial for repairing damaged muscle tissue. So we now know that can't get bigger and stronger without muscle building protein; the next step is to find out the best source of it. Given below, I've outlined a list of food sources that can provide you with a powerful protein-packed punch and can help you maximize your muscle gains. Eggs - One of the best quality sources of muscle building protein is eggs, and they need not be consumed in the ...

  • molecular docking simulation: multiple ligand simultaneous docking A MLSD multiple ligand simultaneous docking example: docking of substrates FAD and PO4 simultaneously to E. coli PNP Purine nucleoside phosphorylase (PNP) catalyzes the reversible phosphorolysis of purine nucleosides. E. coli PNP has been tested for cancer suicide gene therapy. The hexameric PNP has six homo-monomers arranged in an alternative up/down fashion around the central disc, with three of the active sites near the top and the other three near the bottom. The dimer subunit of PNP contains two deeply buried active sites, one near the top and the other near the bottom. We used substrates 2-fluoroadenosine (FAD) and phosphate (PO4) as ligands, and the dimer subunit of PNP as host for multi-ligand docking validations (PDB ID 1PK9). Docking with LGA algorithm found a few distinct conformational clusters. The lowest energy found was -14.2 kcal/mol with the conformational cluster where both FAD and PO4 docked to the same active site near the top of PNP dimer (the movie only shows a monomer for viewing effect). The docked structure aligned very well with the crystal structure binding modes. FAD and PO4 contributed a binding energy of -8.0 kcal/mol and -6.2 kcal/mol respectively. The interaction of FAD and PO4 accounted for an energy of -0.6 kcal/mol. Alternatively, both FAD and PO4 occupied the active site near the bottom with a mean binding energy of -11.2 kcal/mol, showing the asymmetry of the two active sites. Interestingly, the most populated conformational cluster ...

  • Pasta Makes You Row Fasta! Carbohydrates are considered sugars, and there are three types: monosaccharides, disaccharides, and polysaccharides. Monosaccharides are mainly used to provide energy for the cell. Some examples of monosaccharides are glucose and fructose, which are monomers. Multiple monomers linked together create polymers. When two monosaccharides, such as sucrose and lactose, come together through dehydration synthesis, they create disaccharides. In dehydration synthesis, a water molecule is added, and an enzyme links two monosaccharides together. Disaccharides are for the most part readily soluble in water. Disaccharides are broken down through a process called hydrolysis, in which a water molecule is removed and an enzyme breaks apart the monomers. The third type of carbohydrate, polysaccharides, are found in starches, which are made up of repeating subunits of glucose, and are broken down through a complicated process. Examples of polysaccharides include cellulose in plants, as well as chitin in fungi and insects. Presented by Afra K., Angie T., and Shoshana C.
  • hydrolysis of starch Our video displays the break down of starch through the childhood game Red Rover. The starch starts off as a polysaccharide, meaning it is made up of more than one molecules linked together through hydrogen bonds. We simulated this by having 5 students form a chain and connect by linking arms. Then 2 students ran through the student's arms thus imitating hydrolysis (the chemical breakdown of a bond through an enzyme). The two students running through acted as the enzyme amylase, and broke down the starch into disaccharides. The chain of humans was broken down into now two different chains. We then had students once again run through these chains, but this time acted as the enzymes maltase breaking down the disaccharides into monomers. Thus, breaking down the entire chains until the monomers were no longer connected but were single units of glucose.

  • Metabolism Or, Anna's Tower and Its Untimely Destruction. You'll remember the difference between Anabolism and Catabolism with this playful science mnemonic. No cats were injured during the making of this video. Commemorates 2000 views of "My Benzene Ring." Thank you! When you see Anabolic think Anna builds with blocks. An anabolic process takes small molecules, or monomers, and adds them together into a macromolecule or polymer. This is a lot like our friend Anna here, taking blocks and making a tower. So, sugars become polysaccharides, amino acids become polypeptides (which then fold into proteins), and nucleotides become nucleic acids (DNA or RNA). Youll probably get an extra point if you remember that the process is called dehydration synthesis, because when the monomers covalently bond together, it releases water. But, if you can just remember that Anna builds towers out of blocks, youll be on your way. When you see Catabolic, think Cat breaks down block towers. A catabolic process takes large molecules or polymers and breaks them back down into the small. Hydrolysis (or cutting bonds with water) is the opposite of dehydration synthesis.

  • Glucose And Its Effects On Diabetic Metabolic Homeostasis Video made by Chris Bryson, Constantinos Gioiulekas, Julia Goodman, Annie Wilcox Glucose provides energy to start the metabolic process. It is a monosaccharide that is used for ATP production. Glucose is a carbohydrate obtained from food. The starch in food is broken down in stages by the enzymes amylase and maltase into 6 glucose monomers. Then monomers then in turn are used to create the ATP. In the presence of oxygen, glucose is used for aerobic metabolism. Glucose produces CO2 and 36 molecules of ATP through aerobic metabolism. When a person has low levels of ATP their blood glucose levels are low, this is known as hypoglycemia. This occurs specifically in people who are diabetic if they have irregular meal times or over exercise. People who are diabetics have cells that remove glucose to quickly because of their high insulin levels. If they miss meals and/or work out to intensely their body won't have enough glucose to produce the ATP or energy that is needed.
  • Plastic from corn 1955 Plastics are synthetic materials, which means that they are artificial, or manufactured. Synthesis means that "something is put together," and synthetic materials are made of building blocks that are put together in factories. The building blocks for making plastics are small organic molecules - molecules that contain carbon along with other substances. They generally come from oil (petroleum) or natural gas, but they can also come from other organic materials such as corn, wood fibers or banana peels! Each of these small molecules is known as a monomer ("one part") because it's capable of joining with other monomers to form very long molecule chains called polymers ("many parts") during a chemical reaction called polymerization. As a raw material, corn is replacing petroleum in many industrial applications, from plastic containers to clean-burning ethanol. This clip is from the 1955 film, American Harvest, produced by the Chevrolet Division of the General Motors Corporation. The entire film is available on the Internet Archive.
